(AP) — Police chief Norman Williams says he made the final decision to order a shot that ended a 32-hour standoff last week at a Wichita apartment complex.

Williams told reporters Monday that authorities had tried numerous times to negotiate with the suspect. He says the decision to “take him out” was based on the man firing shots earlier at Kmart store and at officers during the ensuing standoff. He also noted the length of the standoff.

The police chief declined to say who took the kill shot because the investigation is continuing.

Authorities used water pressure cannons to knock down sheet rock to see inside the barricaded apartment and explosive devices to gain entry.

The Reno County sheriff is leading an ongoing investigation into the incident.
